1.1 Important information
ATTENTION!
During start-up, observe the respective national safety regulations and
the applicable VDE safety regulations, particularly VDE0100, as well as
the technical connection requirements of the utility company (EVU) and
network operator!
ATTENTION!
This device must only be opened and installed by a certified electrician
according to the corresponding circuit diagram in the casing cover / on
the casing / in the operating instructions. The relevant safety regulations
must be observed. Caution! Operation close to devices which do not
comply with the EMC guidelines can interfere with the functioning of the
device. After installation, the specialist carrying out the installation must
instruct the operator in the functioning and operation of the regulation.
The operating instructions must be kept in a location which is freely
accessible for the operating and service personnel.
ATTENTION!
Only one Smart-RTC must be connected per heat pump manager. A
screened cable of 2 x 0.25mm² must be used.
ATTENTION!
If a Smart-RTC is used, no other device must be
connected to the RS 485 interface (field card).
1.2 Intended use
This device is only intended for use as specified by the
manufacturer.
Any other use beyond that intended by the
manufacturer is prohibited. This requires the user to abide by the
1.3 Legal regulations and directives
Construction and design fulfil all valid EU directives, DIN and
VDE regulations.
When connecting the room temperature controller to the power
supply, the relevant VDE, EN and IEC standards must be
fulfilled.
Persons, especially children, who are not capable of operating
the device safely due to their physical, sensory or mental abilities
2 General
In combination with the heat pump manager, the Smart-RTC
(room temperature controller) controls the room temperature of a
reference room by adjusting the return temperature. The
temperature sensor is integrated into the device. The heating
circuit of the reference room must not be closed off with a valve.
For the cooling operating mode in the heat pump, the Smart-RTC
with humidity sensor must be used. The cooling function is
interrupted by the Smart-RTC if the dew point is not reached. The
Smart-RTC is available in a surface-mounted (RT(H) Econ A)
and a flush-mounted version (RT(H) Econ U).

ATTENTION!
To ensure that the frost protection function works properly, the heat
pump manager and the extension modules must remain connected to the
power supply at all times.
ATTENTION!
Extra-low voltage is applied at terminals Rx + / Tx+ / Rx- / Tx- and GND of
the Smart-RTC. Line voltage (230 V~) at these terminals destroys the
electronic components of the controller
ATTENTION!
Room temperature regulation with Smart-RTC is possible from heat pump
manager software version L01 and Bios version 5.08 onwards.
ATTENTION!
Work must only be carried out by qualified personnel. Before carrying out
any work, always ensure that there is no voltage present at the terminals.
ATTENTION!
If communication cannot be established, the address set on the Smart-
RTC must be checked. WPM software version L03 requires Address 1;
from version L04 Address 50 must be set on the Smart-RTC.
